 PVC hot shrinkage film production in, increase agent is PVC hot shrinkage material processing in important additives 之一, it can reduce polymer separation function force, increase polymer can property, can improvement PVC molding property can. increase agent use amount can more, 否则会 reduce film force property can, make film shrinkage force decrease small, shrinkage rate to effect/influence. increase agent add amount relatively less, therefore comparison difficult, using/adopting improve/increase temperature degree methods also add large PVC hot separation understanding can can property.

  therefore can in formulation in add amount ACR processing modifier can improvement processing properties. ACR and PVC resin solvent understanding degree parameters versus 近, versus property good, viscous force large, ACR hardness ratio PVC large, in 一定应 force function lower, generate relatively large scratch force, from make PVC pellets more easy and melt, improve/increase material material 凝胶化 speed degree and melt quality, melt strong/high degree high.

  lubricant in polymer processing in is non important, in pvc hot shrinkage film production in need add amount lubricant, decrease/reduce has scratch, reduce interface viscous force, according to lubricant function mechanism, adjustment inner, outer lubricant use amount, reduce combined cost. hard acid and oxidized polyethylene wax separation upper belt/tape has and 羟基极 property 基团, can significantly improvement PVC versus property, tool has inner outer lubricated 效果.

  oxidized polyethylene wax OA9 is types polymer/macromolecule oxidation polymerization high temperature lubricant, separation in has amount and 羟基, is types property can function property processing additives, as is lubricant, its chemical property stability, electrical property can good.
